Title: Textile fibre opening apparatus
IPC: D01G23/04
Filed: 1974-05-01
Abstract: 1469949 Weighing out textile fibres TOYODA JIDOSHOKKI SEISAKUSHO KK 1 May 1974 [9 May 1973 (2)] 19052/74 Heading G1W A machine for opening and weighing out textile fibres comprises a weighing device 45 having a weighpan 46, a hopper 8 for the fibres, a belt 9 for lifting fibre tufts from the hopper 8 to a feed chute 27 for the weighpan, an evener cylinder 14 for preventing tufts above a certain size passing to the weighing device, a doffer 26 for stripping the fibre tufts from the belt 9 into the chute 27, means 16 for selectively reducing the gap between the belt 9 and the evener cylinder 14, means for actuating the gap reducing means in response to a predetermined intermediate weight in the weighpan and means for opening the weighpan in response to a predetermined final weight in the weighpan. Fibres are introduced into hopper 8 via belts 4, 7 and a feeler 11 acts on a limit switch (not shown) to switch off the drive to belt 4 when a predeter-  mined bulk of fibres is present in hopper 8. Fibres picked up by evener cylinder 14 are stripped by roller 15 and fall into the hopper 8. Cylinder 14 is carried by a pair of arms 16 pivoted at 17 and drivable by means of a motor 19 to vary the gap between the cylinder 14 and belt 9. Motor 19 rotates threaded rods 23 which carry nut members 25 having arms 25a engaging slots 16d in the arms 16. When the predetermined intermediate weight of tufts has been deposited in the weighpan, a device 51 actuates motor 19 to reduce the gap between belt 9 and cylinder 14 until nut 25 engages a limit switch 60. When the predetermined final weight of tufts has been deposited in the weighpan a device 55 acts via a timer switch to disengage a clutch 40 to stop the drive to belt 9, to operate a mechanism 58 for opening the weighpan, and to operate a solenoid 62 to move a closure flap 28 into the chute 27. After the interval set by the timer switch, clutch 40 again drives belt 9, the weighpan closes, and flap 28 moves to the open position. During the interval, a relay alters the electrical connections to motor 19 so that it rotates in the opposite direction to widen the gap between belt 9 and cylinder 13 until nut 25 engages limit switch 61. In a modified form of the machine the speed of belt 9 may be progressively reduced to a low value in the period during which the gap between belt 9 and cylinder 14 is being reduced, or just before or after that period. In the form described with respect to Figs. 8 to 10 (not shown) the first device 51 actuates a device 71 driving the clutch 40 to reduce the speed of the belt 9 to a low value determined by a limit switch 72 in device 71. When limit switch 72 operates, motor 19 is acuated to reduce the gap between belt 9 and cylinder 14. In this embodiment, the clutch 40 may be omitted and the belt 9 driven at the low speed while the weighpan is emptied. Several machines may operate to disperse predetermined weights of different fibres to be blended on to a common conveyer Fig. 1 (not shown) feeding a spinning machine.

Title: Improved means for carburetting air and for regulating the supply of fuel to internal combustion engines
IPC: F02M11/00
Filed: 1919-08-01
Abstract: 155,869. Grace, C. J. Aug. 1, 1919. Addition to 144,363. Spray carburettors. -The parent Specification describes a carburettor in which the throttle valve is mounted on a tube to the interior of which fuel is supplied, a number of passages leading from the tube to the periphery of the valve, the tube being slotted to bring more or less passages into action in accordance with the throttle position. The invention consists in placing a block 3 in the induction pipe on the engine side of the throttle valve 2, the block containing a number of fuel-passages 4, a greater or lesser number of which may be brought into action by producing relative rotation between the block and slotted tube or casing by means of variable linkage mechanism connected with the throttle valve. An arm 9 on the tube 7, Figs. 1 and 2, is connected through a link 10 with a pin 11, which may be moved by a Bowden wire 14 along a slotted arm 13 of a bell-crank lever 16 on the throttle-valve spindle. Thus the number of fuel passages in action for any given opening of the throttle-valve may be varied. In a modification, the tube 7 is at the lower end of the block which, it is stated, may take the form of a sleeve. In a further modification, the block or sleeve opens at the constricted portion of an horizontal air passage. In a still further modification shown in Fig. 8, the block 3 is rotatable in a casing 19 the lower end of which communicates with the float chamber 6, the top of the casing being slotted. The block is made in two disc-like parts, one being blank and the other containing the fuel passages 4 connected by a transverse passage 20. As the block is rotated from the throttle valve 2, the passages 4 come progressively into action. Specification 8333/13 is referred to.

Title: Improvements in and relating to heating stoves

Abstract: 256,629. Junkers, H. Aug. 8, 1925, [Convention date]. Addition to 225,147. Casings; heat radiators; gas stoves; baffies.- Comprises means for equalizing the temperature of the outer shell in stoves comprising a directlyheated shell 2 surrounded by an outer shell 3, the latter being heated substantially wholly by radiation from the former, as described in the parent Specification. In the form shown in Fig. 1, a heat-insulating lining 4 is provided in the inner shell in the vicinity of the point of entry of the heating gases, to diminish the heat transmission at this point. With the same object a screen or baffle surrounding the same part of the inner shell may replace the lining 4. Fig. 3 shows a stove in which gills 5, secured either to the inner or outer shell, and increasing in size towards the point of exit of the gases, are employed to increase the transmission of heat and balance the fall in temperature of the gases, Similar gills 7 may also be employed inside theinner shell. In the stove shown in Fig. 9, the inner shell is of inverted U form, the hotter ascending and cooler descending shafts producing an approximately uniform temperature. To increase this uniformity, the shafts may be connected in a heat-conducting manner at points 9,. or over their whole length. In addition, the shafts may expand upwardly, to give an increased radiation surface at the top, and at thepoint of entry of the gases the inner shell may slope, so as to direct the radiated heat over a larger area of the outer shell, as indicated by the arrows. A somewhat similar stove for large rooms comprises an inner shell having a central upcast shaft and two or more downcast shafts, the lower ends of which are connected to an annular channel. The stove may be arranged so that a closed air circulation is formed between the shells, as indicated by the arrows in Fig. 13; gills 8 may in addition be provided at the points in the circulation path remote from the inner shell in order to increase the temperature of the outer shell.
